160 HOT-HOUSE OF REPOTTING, &C. [May. 



Taliera bengalensis, being stronger, is of great utility for 

 covering houses. They do not grow to such immense 

 extent in artificial cultivation, but require large houses to 

 grow them. (Soil No. 12.) 



Crinums, about one hundred species, chiefly stove bulbs, 

 many of them beautiful. Those that are of great celebrity 

 are C. erubescens, pink ; C. scabrum, crimson and white ; 

 C. amabile, purple and white ; the neck of the bulb of the 

 latter is long, is easily distinguished by its purplish colour, 

 and is unquestionably the finest of the genus. Several 

 specimens of it are in our collections. Their flowers are 

 in umbels, on a stalk about three feet high ; corolla funnel- 

 shaped ; petals recurved ; nearly fifty flowers on each stem, 

 and a good plant will produce three stems in one year. 

 They require large pots to make them flower well, and, 

 when growing, should be liberally supplied with water. 

 (Soil No. 12.) 



Crotons. About twenty-eight species, few of them de- 

 serving cultivation; but the genus is celebrated for its beau- 

 tiful C. pictus, leaves oblong-lanceolate, variegated .with 

 yellow, and stained with red, flowers small green, or axil- 

 lary spikes. C. variegatus, variety latifolia, is finer than 

 the original variegatus; the nerves in the leaves are yel- 

 low, and the leaves lanceolate, entire, and smooth. To 

 make them grow freely, give them the warmest part of the 

 hot-house, and drain the pots well. (Soil No. 13.) 



Cycas, four species, generally called Sago palm, as an 

 English name. The plant from which Sago is extracted 

 belongs to another genus, (see Sagus.} C. revoluta is a 

 well known palm, and will keep perfectly well in the 

 green-house. We have seen a beautiful specimen of it 

 which is kept every winter in the cellar ; but those that are 

 kept so cool in winter only grow every alternate year, while 

 those that are kept in the hot-house grow every year, which 

 shows that heat is their element. C. drdnulis is a large 

 growing species ; the fronds are much longer, but not so 

 close and thick. C. glauca is a fine species; the foliage 

 is slightly glaucous. They require plenty of pot room, are 

 much infested with the small white scaly insect, and ought 

 to be frequently examined and carefully washed as pre- 

 scribed in January. (Soil No. 12.) 



Cypripedium insigne is a very beautiful nepal species
